My mother beat me twice that I can remember. The first time was the worst: belt, shoe, a hanger, and I recall she stopped to consider hitting me with a tennis racket. Second time was one of those plastic bats. Neither time did I learn anything and both times it was clear that she was doing it just out of anger and not a desire to teach me much of anything. In those moments, it felt like she hated me and if there was any lesson I learned, it was that people who are more powerful than you can do whatever they want to you. Even people who claim to love you.
Now do I resent my mother for this? No. My mom is one of the most loving and giving people I know and to focus on this would be to ignore the fact that had it not been for her guidance and love, I probably would have killed myself years ago. But I also recognize that I can love my mother to bits while also acknowledging her actions on these occasions as barbaric and cruel.
I think this is where some - not necessarily on, Gaf, but in general - get tripped up on this topic. We think that to acknowledge the actions of our caretakers as abusive (because let's be honest: as much as we roll our eyes at people calling a pop on the hand child abuse, a lot of the shit we brush off as just discipline is fucking abuse plain and simple) would be to label them as monsters. No one want to make that call on their parents (depending on your relationship with them, of course).
But for me, I just accept that my mom is human. She was doing the best she could with what she had to work with and she didn't make all the right calls. I won't ever say I deserved to be beaten, but I'm not going to hold it against her for the rest of my life. Especially knowing that she herself was abused as a child (a fact she didn't fully come to grips with until I was an adult) and was probably just doing what she was taught.
I plan to have kids and I won't ever hit them on account of I hate seeing others in pain. Especially children. I believe there are better ways to teach children right from wrong, and the window where I might consider it effective is so small it's like why bother.
